Hi @David_T
Install imwheel
sudo apt install imwheel
Create the hidden file from /home with the following parameters
nano .imwheelrc
copy and paste the following information. This causes the mouse scroll speed to increase in all applications.
".*"
None, Up, Button4, 3
None, Down, Button5, 3
You can change the number 3 to the number of lines you want to scroll when navigating.
Start imwheel
imwheel
Terminate or kill the process whenever you like
killall imwheel
It worked for me, video link if anyone wants to watch it. The video is not of my authorship. It is in Spanish Velocidad scroll demasiado lento LINUX - YouTube
You can see these same parameters at IMWheel - ArchWiki
